Wikipedia definition
1. Transatlantic tunnelA transatlantic tunnel is a theoretical tunnel that would span the Atlantic Ocean between North America and Europe, and would carry mass transit of some type—trains are envisioned in most proposals. Using advanced technologies, speeds of 500 to 8,000 kilometres per hour (310 to 5,000 mph) are envisaged. Plans for such a tunnel have not progressed beyond the conceptual stage, and no one is actively pursuing such a project.
